More than being against all forms of power generation, I get the sense that they're enemies of industrial civilization itself, or in some cases the entire human race. I think there's a subset of "environmentalists" who would be very pleased if mankind vanished from the face of the earth.
They don't care about society. All they care about is "biodiversity" and "the environment". Pragmatism does not enter into their thinking in any way, at least about creatures other than themselves. They don't give a damn about human survival, except their own.
Funny, if you compared these people to the so-called robber barons of the early 20th century you'd probably get punched in the face, but that comparison points out the prevailing attitude - the public be damned, so long as raptors and big-horn sheep don't get waxed.
Un-freaking-believable.
